Frequently Asked Questions
Will my JPG gain transparency when converted to PNG?
The conversion preserves the original image content. If your JPG had no transparency, the PNG will have an opaque background, but you can now add transparency in an image editor.
Will the file size increase when converting JPG to PNG?
Yes, PNG files are typically larger than JPG because PNG uses lossless compression. Expect the file to be 2-5x larger.
Is there any quality loss converting JPG to PNG?
No quality is lost in the conversion. However, any compression artifacts already in the JPG will remain since they cannot be reversed.
Why would I convert JPG to PNG?
PNG is better for images that need transparency, sharp text, or lossless editing. It is ideal for logos, screenshots, and graphics with crisp edges.
